To run the code, modify the two config files, execution.cfg and conf/topology.cfg and execute ./main.py from the root dts folder. Here's an example config: cat execution.cfg [Execution1] sut=127.0.0.1 cat conf/topology.cfg #Topology Configuration #[SUT IP] # sut_ip: SUT ip address # sut_user: SUT username # sut_passwd: SUT password [127.0.0.1] sut_ip=127.0.0.1 sut_user=root sut_passwd=a The code only connects to a node. You'll see logs emitted to console saying where DTS connected. There's no documentation, as there's not much to document - the above is basically all there is to it, as far as user docs go. We'll add some real docs when there's enough functionality to document, when the HelloWorld testcases is in (point 4 in our roadmap below). The config parser will be reworked in near future, so there's no need to review it. While we're working on it, let's review the rest of the code. This is our current roadmap: 1. Review this patchset and do the rest of the items in parallel, if possible. 2. Finish the config parser rework. 3. Rebase this patch on top of 2 and send a new version (along with addressed review comments). 4. We have extracted the code needed to run the most basic testcase, HelloWorld, which runs the DPDK Hello World application. We'll split this along logical/functional boundaries and send after 1 is done. In fact, 1 is part of 4. 5. Once we have 4 applied, we'll planning on adding a basic functional testcase - pf_smoke. This send a bit of traffic, so the big addition is the software traffic generator, Scapy. 6. After 5, we'll add a basic performance testcases which doesn't use Scapy, but Trex or Ixia instead. 7. This is far in the future, but at this point we should have all of the core functionality in place. What then remains is adding the rest of the testcases.
